The worldwide media is not being so kind to President Obama. I guess the HopeyChangey fever is wearing off on the world stage.
But his speech offered no indication America was ready to embrace bold measures, after world leaders had been working desperately against the clock to try to paper over an agreement to prevent two years of wasted effort — and a 10-day meeting — from ending in total collapse.
Obama, who had been skittish about coming to Copenhagen at all unless it could be cast as a foreign policy success, looked visibly frustrated as he appeared before world leaders.
He offered no further commitments on reducing emissions or on finance to poor countries beyond Hillary Clinton's announcement yesterday that America would support a $100bn global fund to help developing nations adapt to climate change.
He did not even press the Senate to move ahead on climate change legislation, which environmental organisations have been urging for months.
The president did say America would follow through on his administration's clean energy agenda, and that it would live up to its pledges to the international community.
"We have charted our course, we have made our commitments, and we will do what we say," Obama said.
But in the absence of any evidence of that commitment the words rang hollow and there was a palpable sense of disappointment in the audience.
